redis.io NS Lookup

//01

What Are redis.io's Nameservers?

NS (Name Server) records for redis.io identify the DNS servers that hold the authoritative DNS zone for this domain. When a recursive resolver needs to look up any record for redis.io — whether an IP address, mail server, or TXT record — it contacts these nameservers to get the definitive answer.

Every domain must have at least two nameservers for redundancy. If one nameserver for redis.io goes offline, the remaining nameservers continue answering queries so the domain stays reachable. Most DNS providers assign multiple nameservers spread across different networks and geographic locations.

The nameservers for redis.io are set at the domain registrar and are part of the delegation chain that makes DNS work. Changing these nameservers is how you switch redis.io's DNS hosting from one provider to another.

How DNS Delegation Works

NS records create the hierarchical delegation chain that makes DNS work. The root DNS servers delegate to TLD servers (e.g., .com servers), which delegate to redis.io's authoritative nameservers via NS records. Each level points to the next, allowing any device on the internet to resolve redis.io to its IP address.

When you update nameservers at your registrar for redis.io, you're changing the delegation at the TLD level. This tells the .com (or other TLD) servers to direct queries for redis.io to a new set of nameservers. This change can take up to 48 hours to fully propagate due to DNS caching.

Who Hosts DNS for redis.io?

An NS lookup reveals redis.io's DNS provider from its nameserver hostnames. Cloudflare uses *.ns.cloudflare.com, AWS Route 53 uses *.awsdns-*.com, Google Cloud DNS uses ns-cloud-*.googledomains.com, DigitalOcean uses ns*.digitalocean.com, and many registrars like GoDaddy, Namecheap, and Google Domains provide their own nameservers.

Knowing the DNS provider for redis.io is useful for troubleshooting resolution issues, understanding the domain's infrastructure, or evaluating the reliability of its DNS hosting. Enterprise-grade DNS providers like Cloudflare and Route 53 offer features like DDoS protection, anycast routing, and sub-second propagation.

Why Nameserver Redundancy Matters

If all nameservers for redis.io become unreachable, the domain effectively disappears from the internet — websites won't load, email won't deliver, and all services depending on DNS will fail. This is why every domain should have nameservers on at least two separate networks.

Major DNS outages like the 2016 Dyn attack demonstrated what happens when nameserver infrastructure fails. Modern DNS providers mitigate this with anycast routing, where the same nameserver addresses are served from dozens of data centers worldwide. redis.io's nameservers indicate how many are configured.

Frequently Asked Questions

Who hosts DNS for redis.io? — redis.io's nameservers reveal its DNS hosting provider. Look at the nameserver hostnames to identify the provider (e.g., cloudflare.com, awsdns, etc.).

How many nameservers does redis.io have? — The number of NS records indicates how many nameservers serve redis.io. Most domains have 2–4 nameservers for redundancy and performance.

What DNS provider does redis.io use? — The nameserver hostnames identify the provider. Compare them against known DNS provider naming patterns to determine who manages DNS for redis.io.

How do I change nameservers for a domain? — Nameserver changes are made at the domain registrar (not the DNS provider). Log into your registrar account, find the nameserver settings, and update them to the new provider's nameservers. Propagation takes up to 48 hours.
